Question about Alpine PDX-1.1000 1000W x 1 Car Amplifier Car Audio Amplifier

1 Answer

2 svcs I have 2 jl audio w3 v3 2 ohms wired together, Is there a waty for my Apline MRP-M650 class D 1 channel 400 watts at 2 ohms X 1 600 watts at 2 ohms X 1 How can I get my amp to see a 2 ohm load with me wiring both of these together? I believe parrallel gives me 4 ohms and series gives me a 1 ohm load this would be my only options correct? Im basically only capable of getting half my amps capacity? Im a little bit confused any help is appreciated thanks

You've pretty much hit the nail on the head. Two 2 ohm subs in parallel would give you 1 ohm, and two 2 ohm subs in series would give you 4 ohms. 1 ohm would be overloading the amp but 4 ohms is slightly "underloading" the amp.

Your best solution with the gear you have (i.e. not buying new subs or a new amp) is to put the subs in series (4 ohms). True, you'll be putting about 200W into each sub, but according to page 4 of the owner's manual for the subs, 200W is just a tad under the optimum level recommended for the sub anyway.

About Power supply wires (MRP-M1000 only)

• 21mm2 is the minimum power and ground cable size

that should be used to connect this amplifier. The

length of these cables should not exceed 1m to assure

safe operation.

• If the length of the power and ground cables exceed

1m, or if you connect more than one amplifier, a distribution

block should be used with 33mm2 or 53mm2

power and ground cables depending on the length

necessary. Ensure that you install a correctly-rated

in-line fuse on the power cable near the battery positive

post.

I got to 12 they are about 400 watts each what would be a good amp to put on it to lift the subs


Hello jeremymikjha,

Basically you want to match the subs in impedance and power.

With 4 ohm subs wired in parallel, the final load will be 2 ohms. Depending on how hard you want them to hit, a pair of 400 watt RMS subs will need an amp that delivers 600-1,000 watts into a 2 ohm load.

The enclosure you use will also make a big difference. A sealed enclosure will need more power. A ported enclosure will be louder with less power.

The Hifonics shown here would be a good choice for a sealed enclosure. It's rated for 1,100 watts RMS into a 2 ohm load.

http://www.sonicelectronix.com/item_17598_Hifonics+BXi+1610D.html

The Eclipse XA1200 outputs 600 watts RMS into a 2 ohm load. It would power the subs very well in a ported box.

http://www.sonicelectronix.com/item_17598_Hifonics+BXi+1610D.html

Somewhat less expensive but good quality would be one of the Alpine MRP series. The MRP-M500 is only $179.99 at SonicElectronix. It delivers 500 watts. It's big brother is the MRP-M1000 with twice the power. Be sure your subs are securely mounted or this amp will literally "lift the subs".

Hope this helps.

Is a 15 w3 d-4 better then a jl audio w3-d2


Hello,

All of the JL W3 subwoofers are essentially the same. The "d2" and "d4" suffix refers to the voice coil configuration. "d2" = dual two ohm coils, "d4" = dual four ohm coils. Depending on the number of subwoofers in your system and the amplifier(s) you are using to power them, one or the other of the configurations may be "better".

Generally, you want to have the load on your amp to have the lowest possible impedance consistent with the amps capability to operate properly with that load. It's normally referred to as "impedance matching". Greater power (watts) is produced, and louder sound, when the amp can deliver power at a lower impedance.

If your amp is only capable of supplying power at 4 ohms, you want to make sure that the configuration of your sub(s) represents a 4-ohm load. If the load is higher, say 8 ohms, then your amp can only deliver about half the power of which it is capable. It would be OK to run them a 8 ohms, but they would not be as loud. On the other hand, if the load was lower, say 2 ohms, your amplifier would soon overheat and go into protect mode.

So the trick is to first decide on how many subs you want. Then choose an amp/sub combination that "matches".

The DVC or dual voice coils just gives you more options in selecting and configuring. Say you want 2 subs and you are going with the 15w3 d-2. Your amp is the JL Audio G-MAX monoblock. The amp puts out 1200Wx1 Chan. at 2 ohms or 600Wx1 Chan. at 4 ohms. You would wire both of your subs voice coils in series making each sub 4 ohms, then wire the 2 subs in parallel to your amp making the final load 2 ohms, the best "match" for your amp.

Ohm load???


You can't wire a pair of single voice coil 2ohm subs to achieve a 2 ohm mono load. Too bad you don't have 2 four ohm SVC's. Sorry

12 w 3 v3 2 cut off


Again as I have stated in my other answer to you. You can not wire two SVC 2 ohm subs to acheive a 2 ohm load. more than likely you are running your amp at 1 ohm mono and this is why it is clipping and shutting off.
